The 'Mission Impossible' actor thinks it is "wonderful" that 18-year-old Isabella - his adopted child with ex-wife Nicole Kidman - has been given an apprenticeship at Holmes & Yang, The Fashion label owned by his actress wife.

He said: "It's wonderful. Kate's designing and Bella is just working her way up.

"She's an artist, Bella, so it's really great that she gets to work with it. She's loving it."

However, the 48-year-old actor - who also has 16-year-old adopted son Connor with Nicole and five-year-old daughter Suri with Katie - admitted he is not an expert on knowing how his wife's company operates.

He said: "This is my wife's company, so you talk about movie sets with me, I can tell you about that."

Asked about Isabella's role, he added to People: "You've got to go to all these different factories and verify and make sure you get the correct clothes."

Katie established Holmes & Yang with her stylist Jeanne Yang, with the air of creating pieces working mothers can "depend on".

Jeanne said recently: "Sometimes when life gets really busy you don't want to have to think about what it is you're going to wear and you just want to have certain pieces that you know you can just depend on - what are those pieces? - and so that was kind of our challenge.

"Both of us are working moms, so we're pretty busy, and, having a line, being moms and then having our careers is quite a lot."
